Justin Bieber Allegedly Headbutted Staffer At Party

The police are investigating the incident.

Justin Bieber is once again on the wrong side of the law. Media reports claim he reportedly headbutted another guest at a pre-Grammy party last weekend.

It all went down at Serafina, a restaurant in LA, at 2AM. Justin was there because his producer friend was throwing a party.

Justin was supposedly joking around with Disney actor Kyle Massey when a staffer started taking video. Bieber asked the staffer to delete the recording and then they started arguing. That’s when Justin lunged at the guy, according to eyewitnesses.
